Answer:

510064471909788 m²

Step-by-step explanation:

diameter=12742 so the radius r=12742/2=6371=6371*1000=6371000

A=4πr²

A=4π(6371000)²

A=162358564000000π =510064471909788 m²

faust18 [17]

Step-by-step explanation:

Let

c = 11.5 cm

a = 8.9 cm

b = ?

Since this is a right triangle, we can use Pythagorean theorem to find the length of side b:

$c^2 = a^2 + b^2$

$\Rightarrow b^2 = c^2 - a^2$

Taking the square root of the equation above, we get

$b = \sqrt{c^2 - a^2} = \sqrt{(11.5\:\text{cm})^2 - (8.9\:\text{cm})^2}$

$\:\:\:\:=7.3\:\text{cm}$
